Quote -  If you use cpu-only rendering or gpu rendering, does texture collection affect the render speed or not? 

No, there is no speed advantage in using texture collection. I don't know how this idea became even possible. Texture collection is about fitting the textures in memory and about moving the Lux scene. That all there is to it :)

 

Cheers.
